CIS 681

Programming Advice

1. Top Down Design

2. Think first, program later

3. Get something working, then add to it

4. Debugging graphics programs can be hard,Program accordingly

CIS 681

What to expect

1. I teach *algorithms*, not C or C++

2. If you don’t have the prereqs, and can’t keep up, then drop the course; if you do and can’t keep up, see me

3. Ask Questions - give me feedback

4. Use the newsgroup, email me
